Greg Bro!/Uw 09/15/98 Page 3 of 3 . As a part of the work being done on Highway 96, the intersection of Round Lake Road and Highway 96 will be reconstmcted and signalized. The intersection will be shifted to the east and a north leg will be added to the intersection. The north leg would provide access to a mobile home park which is encompassed by 1-35W. US 10 and Highway 96. Figure 2 displays the geometry of the intersection after its reconstruction. For the two background conditions, capacity analyses were conducted using the background traftle volumes and geometry documented previously in Figures 1 and 2. The analysis was done using the SIG"AL9~ software and "Chapter 9: Signalized Intersections" of the HiQhwav CaDacitv 1\!anual (HC!\!). Analyses of both scenarios indicate that the intersection of Highway 96 and Round Lake Road would operate at LOS B under optimized conditions. Table 1 displays the results of these analyses. The development forecasts were created by assigning tramc to the respective background condi,ions until the intersection reached the LOS DIE threshold. Final capacity analyses were conducted using the development forecast tramc volumes and geometry documented previously in Figures 1 and 2. Once again. the analysis was done using the SIGNAL94 software and "Chapter 9: Signalized Intersections" of the HiQhwav CaDacitv Manual (HCM). Table 1 displays the results of these analyses. CONCLUSIONS . Starting with the first background tramc condition, the intersection of Highway 96 and Round Lake Road could accommodate an increase of 1,600 trips in the PM peak hour from the 52 acre site. Starting with the second background tranic condition, the intersection of Highway 96 and Round Lake Road could accommodate an increase an increase of 1,100 trips in the Pl\! peak hour from the 52 acre site, Table 2 provides a summary of the land development options that would generate the respective increases in trame, As can be seen in Table 2, traffic conditions dictate that the 52 acre site could 2ccommodate 740,000 - 1,100,000 square feet of office space or 1,100,000 - 1,600,000 square feet of oftlee/showroom space depending on which background conditions were assumed. This implies th~t the degree of de\ elopmen: which could occur on the site is somewhat dependent on when it would be built, As traffic k\'cls alon; Highway 96 and roadways north of the site incre~se over time, the ability of the intersection to aceonunodate additional tcamc is reduced. Therefore, when considering de\'elopment options for the site, dc\'clopmer,: occurring adjacent to the are~ also needs to be considered along with the time when it is built. For c;:ample. if sites north of the intersection such as the mobile p~rk and the TCAAP site a~e rede\'eloped before the round lake site, the intersection of Highway 96 and Round Lake Road would be i;1\p~cted and its ability L' accommodate tranic would most likely bc minimized. Therefore, if and when proposed dc\'C10pments [0: the round lake sitc and adjacent areas are identified, additional analysis should be conductd to mo~, precisely determine the ability of the Highway 96 and Round Lake Road intersection to accommodate the e;:pectec! tranIc.
